Real-Time Chat That Feels Premium
A WhatsApp/Telegram-grade chat experience built directly into your platform. Clients get push notifications, typing indicators, read receipts, and optimistic sending. Practitioners get a unified inbox with every conversation at their fingertips.
Instant delivery with optimistic UI — messages appear before server confirms, failed sends offer one-tap retry
Read receipts: single check (sent), double blue check (read). Clients always know their message was seen.
Send GIFs inline — Instagram-style picker with trending categories, debounced search, and masonry grid
Push notifications + haptic feedback + sound alerts. Visibility-aware — no alerts when already viewing the chat.
Business hours awareness — portal header shows real-time availability: 'Online', 'Available from 9 AM', or 'Replies on Monday'

Quoted replies with sender attribution and content preview. Makes threaded context clear in long conversations.

Full-text search: 3+ characters triggers instant results with client name, snippet, highlighted match, and timestamp
Edit messages within 15 minutes (practitioner) or 5 minutes (client). Shows 'edited' label — original content not preserved for recipient.
Delete within same time window. Shows 'This message was deleted' placeholder. Soft-delete for audit trail.
Rate limiting: 30 msg/min (practitioner), 10 msg/min (client), 5 GIFs/min. GIPHY API key proxied server-side.
